%X The Raman spectra of Cd(NO3)2,4H2O and anhydrous Cd(NO3)2 are reported. The spectrum of Cd(NO3)2,4H2O is compatible with the known crystal structure Fdd2. The spectrum of the anhydrous salt is complex and indicates that the 16 NO3- ions are on four sites with different potential energy environments and each site is occupied by four NO3- ions. The centrosymmetric space group Pbcm is favoured to the non- centrosymmetric space group Pca21. Multiple-site splitting, site- symmetry splitting and correlation-field splitting are used to explain the complex band structures.
